When browsing Stack Overflow (and Meta), I've noticed a difference between some pages:
Lists of questions under the "question" URL (i.e. when you click the "Questions" button) and associated tabs display the preview content below the title.
Lists of questions outside of this URL (i.e. when you click the Stack Overflow logo) display the preview content in alt-text (when you mouseover the title).
Why is this?
I ask because I wonder why I can't scan over the contents of my "Interesting" list without having to either hover over questions (a second or so before the popup appears), or navigate to the content itself. Maybe there's an option I haven't found.
